Scope

Main Technical Content: 5.1 Flexibility 5.1.1 Locking Operation 5.1.1.1 When tested according to 6.2.1, the lock cylinder should be able to open. 5.1.1.2 When tested according to 6.2.1, the opening torque M1 should not exceed 1 N·m. 5.1.2 Key Insertion and Extraction Force The key insertion and extraction force should not exceed 9.8 N. 5.2 Corrosion Resistance After the corrosion resistance test, the torque applied to the key should not exceed 1.5 N·m, and the lock cylinder should be able to open. Table 2: Corrosion Resistance Performance Level 123456 Test Time / h 24 48 72 96 1 20 24 5.3 Security Performance 5.3.1 The theoretical number of teeth on the key should comply with Table 3. 5.3.2 The key interoperability rate should comply with Table 3. 5.3.3 The tensile strength of the lock cylinder should be tested according to 6.4.4, and the lock cylinder should withstand the tensile force F1 in Table 3 without separating from the lock cylinder body. 5.3.4 The anti-drilling performance of the lock cylinder end face should be tested according to 6.4.5, and the lock cylinder should withstand the anti-drilling time t1 in Table 3. After the test, the dial wheel cannot be rotated under a maximum torque of 5 N·m without using the correct key. 5.3.5 The key strength should be tested according to 6.4.6, and the key should not break after withstanding the torsional torque M2 in Table 3. 5.3.6 The lock cylinder resistance to pressure should be tested according to 6.4.7, and the lock cylinder should withstand the pressure F2 in Table 3 without breaking. 5.3.7 The durability should be tested according to 6.4.8, and the lock cylinder durability should meet the corresponding requirements in Table 3. 5.3.8 The artificial attack should be tested according to 6.4.9, and the lock cylinder should be able to withstand the artificial attack time t2 in Table 3. 5.3.9 The lock cylinder should still be able to function normally after f
